PBGENE-DMD is an investigational first-in-class in vivo gene-editing therapy for Duchenne muscular dystrophy in patients with dystrophin mutations between exons 45-55. It uses a gene-excision approach intended as a one-time treatment to restore near full-length dystrophin production. FDA provided a Study May Proceed notification in February 2026, enabling Phase 1/2 trial site activation.
